Golden Mean Calipers are used by artists, architects, designers, and doctors.
They are hand-crafted in New Zealand and shipped globally. They are made of laser-cut, hand-brushed stainless steel, with brass rivets.
When you order them, you get to talk to the guy who actually makes them. Me :)
They are perfect. A nice blend of laser-cutting and hand work (I can’t imagine how they use a laser to cut shiny stainless steel) – Glen, California
It is beautiful and will live on my workbench to be used daily as I apply the principle of the golden mean to my designing – Bob, Vermont

for the 180mm, medium calipers
Made from Rimu, a native New Zealand timber (sustainably logged etc)… makes a beautiful, light-red/amber grain. The case is two identical halves held together with neo-magnets. Designed by me, and made by a local wood-crafting firm.

180mm long, measuring 35 mm to 320 mm
The medium-sized calipers are the most popular- they have been bought by artists, graphic-designers, engineers, plastic-surgeons and gadget-collectors. I personally use these ones for web-design (to get a “2nd opinion” on balance etc).
They come with silicone tips to avoid scratching screens, people etc.

114mm long, measuring 25 mm to 190 mm
These are the smallest calipers I make – they have been bought by artists, jewellers, plastic-surgeons and collectors of gadgetry. I personally use these ones for web-design (to get a “2nd opinion” on balance etc).
They come with silicone tips to avoid scratching screens, people etc.

400mm long, measuring 80 mm to 750 mm
The large calipers are useful for sculpture, larger-scale engineering and artistic pieces. My dad used them to design some Mondrian-themed tables and chairs for the new princess/granddaughter.
